At the preferred term (PT) level, the impact of age on the occurrence of adverse events (AEs) in patients receiving chemotherapy alone (pemetrexed and platinum). In this forest plot, a confidence interval for an adverse event to the right of the null effect line (ROR = 1) indicates a higher risk for elderly patients (≥ 65 years old), while one to the left indicates a higher risk for younger patients (< 65 years old). Abbreviations: PT, preferred term; ROR, reporting odds ratio; CI, confidence interval
